Spotting micro‐movements in image sequence by introducing intelligent cubic‐LBP
IET Image Processing, Volume 16, Issue 14, Page 3814-3830, 11 December 2022., 2022 Abstract Invisible to naked human eyes, micro‐movements are barely noticeable. There are wide ranges of micro‐movement applications from spotting subtle changes in a volcano, vascular pulse, and blood vessel to micro‐expression detection. In the latter, some evil thoughts can be unveiled, resulting in identifying crooks and lawbreakers and it arises ...
